Theodoros, D.G. & Murdoch, B.E. (1994). Laryngeal dysfunction in dysarthric speakers following severe closed-head injury. Brain Injury, 8(8), 667-684. Type of Study Research study with controls Subjects 17 males, 2 females; ages 21-55; more than 3 months post-onset Gender-matched, age-matched controls Diagnoses Severe TBI Normal controls Speech Condition Dysarthria Purpose To provide a detailed perceptual and physiological evaluation of laryngeal function in severe TBI subjects with dysarthria Methods Perceptual assessment-speech sample analyzed by 2 SLP's for harshness, strained/strangled, hoarseness, glottal fry, and intermittent breathiness Instrumental assessment-electrolaryngographic and aerodynamic techniques Results 16/19 (84%) had some laryngeal dysfunction 3/19 (16%) had no laryngeal dysfunction 19/19 controls had no laryngeal dysfunction Hyperfunctional laryngeal activity from instrumental assessment from spasticity, glottal and respiratory force adjustments, and compensation Inconsistencies between perceptual and instrumental assessments Treatment Implications Need to assess laryngeal function in severe TBI patients with dysarthria Need to do both perceptual and instrumental assessments Therapy for laryngeal dysfunction and consideration of compensatory strategies   Assessment Treatment Speech Characteristics Books and Book Chapters Instruments Other Links Search Home   To return to the Abstract References, click on Assessment , Treatment  , or Speech Characteristics or use your browser to go Back.
